VERSION 1.2 M90, M100, M100
12V Power out (J16)
This is the 12V power out connector. It is the output of the on-board DC converter. The M100-12 has no on-
board 12V DC converter. Here the 12V power in and out connectors are connected together.
Power input (J13)
This is the power input connector. The standard version is the M100-42. It features an on-board DC down
(buck) converter which supports an input voltage of 13.5V to 42V. If the input voltage is less then 13.5V the
12V output voltage may not be stable and it will track the input voltage. For most use cases this actually may
be ok, as the Jetson TX1 can operate with a supply voltage down to 7V. The same is true for the DC converters
on the M100 and J100/J106.
The M100-12 is a special low cost version of the M100. Here the 13.5V to 42V in DC down converter is not
populated and the power in and 12V power out rail are shorted together. For this special version the voltage
input range is 7V to 17V. Please note that the J16 power our connector directly supplies the input voltage.
Alternatively power may be provided via the two 1.5mm holes, where cables may be soldered in.
CAN 2 (J10)
This is the CAN connector which is connected to the SPI to CAN controller on the J100 or J106. The CAN Bus is
driven by a TJA1051TK/3,118 CAN bus transceiver.
